DESCRIPTION FIELD OF INVENTION

The scope of the present invention relates to a reversible baby stroller with a brake structure. The frame of the baby stroller has a reversible handlebar. Besides, the handlebar has an actuated member, and is connected between the actuated member and the brake mechanism through the flexible wire. Further, whether the handlebar is in the position of the front or the rear, the user can use the actuated member to control the brake mechanism.

BACKGROUND

The conventional baby stroller usually has a handlebar for the user to push. The fixed type handlebar is positioned behind the rear of the frame seat in the baby stroller, and is convenient for the user to push the baby stroller from the rear. Further, the rear legs having a brake apparatus, in other words said brake apparatus is positioned on the lower side of the handlebar, which can be controlled for movement and to stop the baby stroller. Since the fixed type handlebar is pushed by the user from the rear of the seat, the baby cannot see the user and feels unsecure and unstable.

Besides, some baby strollers use the reversible handlebar. The handlebar is jointed on the frame, and selectively fixed by either face or back to the baby for further pushing the baby stroller. However, when the handlebar is changed to face the baby as a pushing position, the user is required to choose another side to operate the brake apparatus, and has more trouble in the operation. This is because the original brake apparatus is positioned on the lower side of rear leg. In order to overcome the above problem, some of the front wheel sets have the brake apparatus. However, this method is not only a waste, but also causes confusion and inconvenience to the user. Similarly, the user can not recognize which set has already been released or is in the brake status.

According to the above mentioned descriptions, the conventional reversible baby stroller with a brake structure has an inconvenient operation and expensive cost. The present invention relating to a reversible baby stroller with a brake structure can overcome the above disadvantages. The handlebar in the present invention has an actuated member. The flexible wire is connected between the actuated member and either front or rear brake mechanism, and said actuated member can control the brake mechanism as well as select the baby stroller in either movement or stop status. The actuated member and the flexible wire are both positioned on the handlebar. Therefore, the actuated member moves along the handlebar when the user changes the direction of the handlebar. Further, the user can operate the actuated member through the flexible wire to drive the brake mechanism as well as to achieve convenience.

DETAILED DESCRIPTION OF THE INVENTION (PREFERRED EMBODIMENTS)

Please refer to FIG. 1 and FIG. 2. The present invention relates to a reversible baby stroller with a brake structure. The present invention mainly provides that the user can change the direction of the handlebar (1) either in the front or in the rear of the baby stroller as well as control the same brake mechanism on the handlebar. The present invention comprises a frame of the baby stroller (10), a brake mechanism (2), and a driving mechanism (3).

The above mentioned frame (10) of the baby stroller consists of multiple tubes, and the wheel set (11) is joined with wheel (12) for movement. Besides, it also includes a seat portion (13) for baby to sit. Further, the frame of the baby stroller (10) includes a joint portion (14), a front positioning portion (15), a rear positioning portion (16), and a handlebar (1). Please refer to FIG. 5. The handlebar (1) has a reversible sleeve (17). The end is joined with the joint portion (14) of the frame (10) in the baby stroller. It can use the sleeve (17) on either the front positioning portion (15) or the rear positioning portion (16) to lock for positioning. Therefore, the handlebar (1) rotates and positions in either the front or the rear by the joint portion (14). Further, it can provide the user to choose either face or back to the baby to push the baby stroller for convenience.

Please refer to FIG. 3. The brake mechanism (2) is positioned on the wheel set (11) in the lower side of the frame (10) in the baby stroller, and can control the brake of the wheel (12). In the present preferred embodiment, the brake mechanism (2) includes a wheel base (21), a brakebar (22), and a slider (23). The slider (23) is inside the wheel base (21), and also can slide inside the wheel base (21). The brake rod (22) is penetrated through the slider (23), and moves along the slider (23). The position of the brakebar (22) is changed and forms a lock with the wheel (12), and can prevent the wheel (12) rotating. An elastic member (24) is positioned between the slider (23) and the wheel base (21). By using the electric member (24), the slider (23) and the brakebar (22) return to the released position which is not in contact with the wheel (12). Further, the brake mechanism (2) also can use the brake pad (not shown in the figure). The friction of the contact between the brake pad and wheel (12) makes the wheel speed down or stop.

Please refer to FIG. 4. The brake apparatus (2) can be controlled by a driving apparatus (3). The driving apparatus (3) includes an actuated member (31) and a flexible wire (32). In the present preferred embodiment, the actuated member (31) is positioned on one side of the handlebar (1) as well as joined with the handlebar (1). The user can switch to either a positioning location (311) or a released location (312). Please refer to FIG. 4. In the present preferred embodiment, the positioning location (311) in the actuated member (31) has a lock portion (8). The handlebar (1) has a positioning portion (9). When said actuated member (31) rotates to the positioning location (311), said lock portion (8) uses a spring (7) to push into the positioning portion (9) for said actuated member (31) to remain at a positioning location (311). When the lock portion (8) is away from the positioning location (9), the actuated member (31) again returns to the released position (312).

Please refer to FIG. 6. The above mentioned flexible wire (32) is positioned between the actuated member (31) and the brake mechanism (2). In the present preferred embodiment, the flexible wire (32) is positioned on the inside of the handlebar (1). Further, both ends are individually connected between the actuated member (31) and the slider (23) or the brake pad. The rotation of said actuated member (31) through the flexible wire (32) can drive the brakebar (22) to move. Further, the brakebar (22) can either limit the movement or release the wheel (12). In the present preferred embodiment, the flexible wire (32) is extended to the downside in the inside of the handlebar through the single side of the apparatus. Further, it is connected with a transferred junction (4), and said transferred junction (4) has two flexible branch wires (321) individually connecting with the brake mechanism (2) in both sides. Besides, the actuated member (31) also can be positioned in between the handlebar (1).(not shown in the figure) Further, both sides can extend the flexible wires (32), and said pair of flexible wires (32) are individually connected with the brake mechanism (2).

According to the above mentioned components, the user can select the handlebar (1) positioning either in the front positioning portion (15) or in the rear positioning portion (16) for either facing or backing the baby, and pushing the handlebar (1) to move the frame (10) of the baby stroller. Since the actuated member (31) is positioned on the handlebar (1) and the flexible wire (32) is along the handlebar, the said actuated member (31) and the flexible wire (32) move along the handlebar (1), but do not affect the brake function. When the user wants to brake, the actuated member (31) is first pulled. When the brakebar (22) or the brake pad are pulled through the flexible wire (32), either said brakebar (22) or the brake pad makes the brake on the wheel (12). The said actuated member (31) is positioned in the positioning location (311) as well as being fixed, the said brakebar (22) makes the wheel (22) remain in the brake status. For releasing, the actuated member (31) is also pulled to the released position (312). Further, the elastic member (24) assists the brakebar (22) or the brake pad to release the limitation on the wheel (12).
